State any two limitations of bohr's model
WebAtomic Model. 1. On the basis of the above observation, Rutherford proposed an atomic model as follows. 2. All the protons (+ve charge) and the neutrons (neutral charge) i.e nearly the total mass of an atom is present in a very small region at the centre of the atom. The atom’s central core is called nucleus. 3. WebBohr’s model accounts for the stability of atoms because the electron cannot lose more energy than it has in the smallest orbit, the one with n = 1. The model also explains the Balmer formula for the spectral lines of …

Web•Limitations of the Bohr model: • The Bohr model explains only single-electron atoms and their spectra. • However, the Bohr model did give insight into the quantized behavior of the atom that was later better understood. Modern Model of the Atom: Quantum Mechanics • Orbital = math function describing the probability of finding an electron • Pictures are … WebPostulates of Bohr's atomic model: Bohr assumed that electromagnetic radiation has dual nature which means that radiations have both wave/particle-like properties. As Rutherford's model fails to explain the hypothetical results regarding the atomic spectrum of elements.

The innovative curricular approach of discipline-culture (DC) suggests a way of overcoming its significant difficulties. It suggests presenting QP as a fundamental theory structured in terms of the …
WebIt's all in the definition. The energy is defined as zero when the electron is an infinite distance from the nucleus. As the electron comes closer, the energy decreases, so the energy of the system becomes negative. Even for an H atom in an excited state, the energy is negative, but it is less negative than for an atom in the ground state.
